"ATRSTL did an excellent job! They came out when they said they would, trimmed our trees and removed a 7ft hedge. Their team had all the needed equipment and finished the job in a timely manner. All limbs, bushes and debris were cleaned up and taken with them for disposal. Highly recommend!!"

Arborists FAQs, answered by experts

Generally, you’ll want to prune back the trunk by 1 to 2 feet each year to promote bushy growth. Doing so concentrates vegetative buds closer to the bottom of the tree, where you can easily harvest fruit. For side shoots that are a year old, leave at least six leaves. 

Never remove more than 30% of a tree’s foliage during pruning—even if your tree is really overgrown. Removing this much foliage at a time could kill your tree.

Most jobs take 2-8 hours, but extensive trimming may take multiple days.

Aside from removing dead or diseased branches, you should prune your trees somewhere between every one and three years. Some people—particularly commercial farmers—prune their apple trees yearly to produce higher yields. This is the best way to promote tree health. That said, the average homeowner can get away with hard-pruning their mature apple tree every other year or every three years. 

If you don’t stake a tree that needs support, it could be at greater risk of being damaged or failing completely, whether it uproots or falls over. That could cause damage to your property or other surrounding trees. If you want to grow healthy trees, you may need to stake them for best results.

You need to remove all branches affected by Dutch elm disease. If your tree has several affected branches, you will probably need to remove the entire tree. First, consult a pro to be sure that you’ve correctly identified it as an elm tree. Make sure the tree is properly disposed of with a plastic covering or through debarking, chipping, or burning.
